Different Methods to Show Error Messages In PHP

PHP Errors

We use error functions to deal with error logging and error handling.

Types of Errors:

There are two types of errors:

These are logical errors in code.

These are errors related to the interactions of your code with the outside world.

Dealing with Error:

When we have figured out the error we can use the following ways to deal with them:

Display the Error: This shows the error to the developer and/or user when the program is executed.
Log the Error: Store the errors and review them from a textual log file
Act on the Error: Each program will need a different type of action.
Ignore the Error: This should continually be avoided.

Showing Errors:

There are Four possible ways:

Turn off error reporting:

<?php
error_reporting(0);
?>

<?php

error_reporting(0);

Report all errors:

<?php
error_reporting(E_ALL);
?>

<?php

error_reporting(E_ALL);

<?php
ini_set("error_reporting", E_ALL);
?>

<?php

ini_set("error_reporting", E_ALL);

Report runtime errors:

<?php
error_reporting(E_ERROR | E_WARNING | E_PARSE);
?>

<?php

error_reporting(E_ERROR | E_WARNING | E_PARSE);

Report all Except E_Notice:

<?php
error_reporting(E_ALL & ~E_NOTICE);
?>

<?php

error_reporting(E_ALL & ~E_NOTICE);
